Fire Resistance of Class A Chinese Fire Windows: An In-Depth Analysis
As a leading fire-rated glass supplier based in China, we understand the importance of fire protection in both residential and commercial buildings. One critical component of a building’s fire safety system is the fire window, particularly those equipped with fire-resistant glass. These windows play a vital role in containing fire, smoke, and heat within designated areas. In this article, we will delve into the fire resistance properties of Class A Chinese fire windows, with a focus on their compliance with relevant standards and their performance during rigorous testing.
Overview of Testing Results for Class A Fire Windows
Our fire windows are tested according to stringent Chinese standards to ensure they meet the required fire safety performance. The following are key testing aspects and results that demonstrate the fire resistance of our Class A fire windows.
1. Appearance Quality of Fire Windows
Fire windows must meet precise aesthetic and structural standards to ensure their fire resistance is not compromised. The appearance and installation of the fire window components are strictly regulated to prevent defects like cracks, protrusions, or paint inconsistencies. Specifically, the use of composite fire-rated glass in these windows adheres to GB15763.1-2001 standards, ensuring a flawless visual and physical finish that enhances the window’s integrity in a fire.
- Key Testing Results:
- The composite fire-rated glass used in our fire windows meets the appearance standards of GB15763.1-2001.
- Thickness deviation for single-pane fire-rated glass is kept within the standard tolerance of ±0.0mm.
- Window frame deviations, including height, width, and thickness, are all within the permissible limits.
These results confirm that our fire-resistant windows maintain both aesthetic quality and structural integrity, meeting all relevant safety standards.
2. Air Tightness Performance
The air tightness of fire windows is essential for maintaining fire protection during an emergency. According to GB/T7107-2002, the air-tightness level should not be below Grade 3. This is critical as it ensures that no smoke or gases can pass through the window frame during a fire, preventing the spread of harmful substances throughout the building.
- Key Testing Results:
- Our fire windows meet the Grade 3 air-tightness requirement, ensuring superior performance during a fire.
3. Fire Resistance Performance
The fire resistance of our Class A fire windows is tested to ensure they provide sufficient protection against both heat and fire penetration. The standard requires that Class A fire windows maintain their fire integrity for at least 1.5 hours. Our windows have been subjected to comprehensive fire tests to measure both fire insulation and structural integrity.
- Key Testing Results:
- Fire Insulation: The fire-rated glass used in our windows has a fire insulation rating exceeding 1.5 hours.
- Fire Integrity: During the fire test, the window’s fire integrity remained intact for over 1.5 hours without failure.
- Temperature Rise: The average temperature rise on the unexposed side was 70°C, well within the safe limits. The maximum single-point temperature rise was 138.6°C.
These exceptional results confirm that our fire-resistant glass windows provide top-notch fire resistance, preventing the spread of fire for longer durations.
